I have a growing concern about plastics and potential toxic materials in our kitchenware so I bought a couple of these bottles.
I really like these. Liquids stay cold and I end up drinking more water and feel better simply by being hydrated. Still working to increase my water intake though.

Quality product. Exterior size is about the same as that of the 600 ML Smart Water bottle, so it's easy to grab and drink out of it. But because it's double walled, the capacity is a little less, 500 ML (half liter) like a large beer bottle. May not be large enough for camping but it's perfect as your water bottle at home. The lid screws on and off easily and smoothly, it's not metal against metal. The mouth opening is also just right. Large enough so you can drop ice cubes into it, but still easy to drink out of it. It keeps the water cold. Overall good design.

Beautiful blue - keeps my water cold. Not quite as long as the Element bottle but the price is much better on this one. Now I want one of every color (except pink - gross) but my cabinets can't hold them all Q.Q

I LOVE THIS! "Swell" bottles are all the rage, and this is a great generic alternative. It works AMAZING! This baby will hold piping hot or freezing cold liquids and keep them that way for more than a day. If you want to keep your drink or soup hot all day, this bottle will do it.
PROS:
- Incredibly well-insulated. In my experience, heat/cold stays in for up to 12-18 hours
- The surface of the bottle does not get hot/cold from the drink, so no worries about burning yourself on it
- Does not leak, even if inverted or jostled (I carry it in my backpack every day and it's never leaked)
CONS:
- In a way, the bottle does TOO good of a job. If you pour freshly made coffee into it, a few hours later it may still be too hot to drink. The lip of the bottle is in contact with the liquid, and so you can also burn your mouth on the bottle's lip if the drink is very hot. The best solution I've found to this is either let coffee/soup/tea cool somewhat before putting it in the bottle, leave the top off for a few minutes while it cools down before drinking for the first time, or bring a cup with you to use to actually drink out of rather than drinking directly out of the bottle.
- The color of the actual bottle is not as bright as shown in the product picture. I got the gold bottle, and the color is much more muted. I still like the color though!

I'm picky about water. I need to drink a ton of it, since I'm prone to kidney stones, but I only like drinking it if it's ice-cold. I hate going to take a drink and realizing my water has gone room-temp and the outside of my bottle is wet from condensation. I can't use open containers or glasses because my cat likes to dip her litter-poo paws in and drink MY water, despite having daily fresh water (the same filtered stuff I drink) provided to her.

First World Problems, I know.

The first morning I used this bottle, I filled it with ice from my freezer and continued drinking and refilling it with just water (no more ice) throughout the day. It never got wet on the outside or left a ring on my coasters. When I went to take a drink from it after waking up the next morning, just over 24 hours later, it STILL had ice in it! I've been using it for two weeks now and my husband is getting sick of me telling him how much I love this water bottle when I go to take a drink upon waking up in the morning.

I got the dark wooden printed one because it almost perfectly matches the skins I have on my laptop and phone. The bottle is easy to clean if you have a bottle brush (if not, get one). There's no weird taste or anything when drinking from it (weirdly enough, I think it tastes better than when I drink the same water from plastic water bottles).

I highly recommend this water bottle!

So I got up to fill my water bottle in the middle of the night and, since it was so cold, I turned on our gas fireplace. I was so tired that I accidentally left my water bottle DIRECTLY IN FRONT OF the fireplace and went back to sleep. When I got up in the morning, it was very warm to the touch on the outside, but when I went to see how it was doing on the inside... it still had ice in it! Seriously, I LOVE this water bottle.
